1480nm Polarization Maintaining 3 Ports Optical Circulator
The 1480nm Polarization Maintaining 3 Ports Optical Circulator is a high-performance passive optical device designed to direct light sequentially from Port 1 → Port 2 → Port 3 with minimal loss and high isolation. Built with PM1550 polarization maintaining (PM) fiber, it preserves the state of polarization (SOP), ensuring stable and reliable signal transmission in polarization-sensitive applications.
Optimized for the 1480nm wavelength range, this circulator features low insertion loss, high isolation, and excellent return loss, making it ideal for use in fiber laser systems, optical amplifiers, and advanced optical communication networks. Its compact design and robust performance enable precise signal routing while maintaining high polarization extinction ratio.
